Can we change the 2nd question to read, “Order the non-square rectangles from tallest to shortest?” As a high school Geometry teacher, this is a big pet peeve. Students come to me and literally do not believe me when I tell them that squares are rectangles, and parallelograms, and trapezoids, and rhombuses. When we are not precise with students early on, misconceptions become ingrained making them really hard to fix!
When I taught fourth grade, I did make that clear and I felt like they had a good understanding of it. Now I teach first grade and I feel like that concept would be too out of reach for now.

In Texas we help students understand that squares are special rectangles.
